The function file_first_chars in python takes one parameter, fname, the name of a text file, and returns a string made up of the first character from each line in the file.  You may assume there are no blank lines in the file. Hint: Use a for loop to iterate over the lines of the file and accumulate the string of first characters. NOTE: Return the function, don't print For example: Test Result print(file_first_chars("wordlist1.txt")) hsaem

The function fopen return NULL when: An error occurred while opening the file. An error occurred while reading the file. An error occurred while closing the file. An error occurred while compiling the file.

Range for loop should be used even the block code needs to access index.  Group of answer choices True False

Please follow the instructions The function first_words in python takes one parameter, fname, the name of a text file, and returns a list containing the first word from each line of the file. For example, if the file contents are: apples are red bananas are yellow limes are green then the list ["apples", "bananas", "limes"] should be returned.NOTE: You may assume the file will contain no blank lines.BIG HINT: If line is a string representing a line of text (inside of a for loop!), then L = line.split() creates a list of the words in the line. For example: Test Result L = first_words("snakes.txt") print(L) ['Cottonmouth', 'Timber', 'Black', 'Tiger', 'Copperhead', 'Eastern', 'Western', 'Eastern', 'Prairie', 'Mojave']
